<h3>Notes:</h3>
<p style="direction:ltr;"><font color="#000000">I would like to start with the contributions of this project.</font></p>
<p style="direction:ltr;"><font color="#000000"></font></p>
<p style="direction:ltr;"><font color="#000000">I designed and implemented a new user space data transport protocol for high performance data transfer over the emerging high speed wide area optical networks. The implementation is an open source library with production quality. It has been used by many research institutes and anonymous users.</font></p>
<p style="direction:ltr;"><font color="#000000"></font></p>
<p style="direction:ltr;"><font color="#000000">I designed the UDT congestion control algorithm that can be used for efficient and fair data transfer in distributed data intensive applications. I also proposed several techniques to deal with packet losses. In addition, I employed bandwidth estimation technique in the congestion control.</font></p>
<p style="direction:ltr;"><font color="#000000"></font></p>
<p style="direction:ltr;"><font color="#000000">Finally, I also expanded the UDT implementation to become a configurable transport protocol framework. The Composable UDT allows users to easily implement and evaluate new control protocols.</font></p>
<p style="direction:ltr;"><font color="#000000"></font></p>
<p style="direction:ltr;"><font color="#000000">I have done extensive evaluation work using simulations, experiments, and real world applications.</font></p>
